The Methane Mystery
|
| Topic: Titan |
12/10/05 |
| The methane giving an orange hue to Saturn's giant moon Titan likely comes from geologic processes in its interior according to data from the Huygens Probe. Huygens, which descended through the moon's thick atmosphere on Jan. 14, 2005, also found evidence of liquid methane in the surface material. |

| If there is life on Saturn´s moon Titan, it's not producing all that methane in the atmosphere. That is one conclusion in a series of Cassini/Huygens mission reports published online this week by the journal Nature. |

Titan's Rocks of Ice
|
| Topic: Titan |
11/07/05 |
| Saturn's giant moon Titan is so cold that, on its surface, water is as hard as a rock - literally. Chris McKay, a planetary scientist at NASA Ames Research Center, recently gave a public lecture, sponsored by the Planetary Society, about what scientists have learned about Titan from the European Space Agency's Huygens probe. |

Radaring Titan
|
| Topic: Titan |
11/05/05 |
| The Cassini spacecraft carried the European Space Agency's Huygens probe to Saturn and released it in December 2004. The probe landed on Titan Jan. 14, 2005, acquiring a set of images using the descent imager/spectral radiometer camera as it parachuted to the surface. As Cassini continued to orbit Saturn, its imaging science subsystem and visual and infrared mapping spectrometer mapped the region where the Huygens probe landed. On Friday, Oct. 28, 2005, Cassini's radar instrument provided the highest resolution orbital data yet of this area. |

Titan: Greenhouse and Anti-greenhouse
|
| Topic: Titan |
11/03/05 |
| Earth, Mars and Venus all have greenhouse effects. So does Saturn's giant moon Titan. But Titan also has an anti-greenhouse effect. Chris McKay recently gave a public lecture, sponsored by the Planetary Society, in which he talked about the scientific results of the Cassini-Huygens mission to Saturn and Titan. |
